CC   -!- FUNCTION: Catalyzes the epimerization of the S- and R-forms of
CC       NAD(P)HX, a damaged form of NAD(P)H that is a result of enzymatic or
CC       heat-dependent hydration. This is a prerequisite for the S-specific
CC       NAD(P)H-hydrate dehydratase to allow the repair of both epimers of
CC       NAD(P)HX. {ECO:0000255|HAMAP-Rule:MF_01966}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(6R)-NADHX = (6S)-NADHX; Xref=Rhea:RHEA:32215,
CC         ChEBI:CHEBI:64074, ChEBI:CHEBI:64075; EC=5.1.99.6;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01966};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(6R)-NADPHX = (6S)-NADPHX; Xref=Rhea:RHEA:32227,
CC         ChEBI:CHEBI:64076, ChEBI:CHEBI:64077; EC=5.1.99.6;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01966};
CC   -!- COFACTOR:
CC       Name=K(+); Xref=ChEBI:CHEBI:29103;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01966};
CC       Note=Binds 1 potassium ion per subunit. {ECO:0000255|HAMAP-
CC       Rule:MF_01966};
CC   -!- SIMILARITY: Belongs to the NnrE/AIBP family. {ECO:0000255|HAMAP-
CC       Rule:MF_01966}.
